Here is a plan proposed by Don Johnson in the first turn for the artillery barrages:

"Here is my 20-year-old artillery plan. It has no contingency planning, so I am sure it can be improved by using if..thens. Everything fires hurricane and these are what column is used after all modifications. 1. 18 drumfire on 2319. 2. 32 rolling on 0811 3. 24 drumfire on 1620 4. 32 rolling on 1421 5. 32 rolling on 1523 6. 32 rolling on 1525 7. 26 drumfire on 1921 8. Leaving not fired 0402, HART.

My notes say to have KEH (0-1-12) try for Cambrai hex 2316 along with cav. art. This implies that the unit in 1921 is a key lynchpin unit to at least reduce to cadre before the 2nd British movement phase. And of course, the 3 32 rolling barrage attacks plus combat is supposed to create a hole in the front line ZOCs somewhere."
